How to pick backend framework for node, When to Use Next.js as Backend and When to Use Express.js

In the world of backend development, selecting the ideal framework can be pivotal to your application's success. Next.js and Express.js stand out as prominent contenders, each offering distinct advantages tailored to different project needs.

Next.js boasts seamless integration with React.js, making it an attractive choice for projects already utilizing this frontend library. Its opinionated approach simplifies server-side rendering (SSR) and static site generation (SSG), perfect for content-driven websites or blogs where performance and SEO are paramount. Additionally, Next.js' opinionated defaults streamline development, allowing you to focus more on coding and less on configuration.

On the other hand, Express.js offers unparalleled flexibility and performance, particularly suited for complex applications with intricate backend logic or microservices architecture. When high CPU usage is a concern, Express.js shines with its efficient handling of intensive computational tasks, thanks to Node.js's event-driven architecture. Moreover, Express.js excels in building RESTful APIs, providing robust routing and middleware support for scalable backend services.

Ultimately, your choice between Next.js and Express.js hinges on factors such as project complexity, performance requirements, and development preferences. Whether you prioritize simplicity and integration with React.js or seek flexibility and performance optimization, understanding the strengths and use cases of each framework will guide you towards the right decision for your project's backend architecture.

Book Review - "A History of Western Philosophy" – A Personal Review and Reflection

Reading Bertrand Russell’s A History of Western Philosophy felt like stepping into the grand, winding corridors of Western thought — with Russell himself as your witty, insightful, and occasionally snarky guide. I didn’t open this book expecting to agree with everything. What I wanted was clarity, structure, and a sense of how all these big thinkers across the centuries connect. And that’s exactly what this book delivered, with a tone that balances intellect and irreverence brilliantly. Russell doesn’t just list philosophers. He sketches their ideas, yes, but also their lives, their contradictions, their blind spots. From the ancient Greeks to the modern rationalists, he doesn’t hesitate to praise where it's due, but he also critiques with surgical precision. He brings Plato, Aristotle, Aquinas, Descartes, Spinoza, Hume, Kant, Nietzsche — and so many more — into sharp, readable focus. What makes this book stand out to me is that Russell writes as both a philosopher and a histor...

How does JWT Authorization works

When a user logs into the application, they provide their username and password to the backend. The backend verifies these credentials and, if they are valid, generates a JSON Web Token (JWT) containing information such as the user's ID and roles. This JWT is signed with a secret key unique to the server and sent back to the client. The client securely stores the JWT, commonly in browser storage or as an HTTP-only cookie. When the user attempts to access protected resources or perform specific tasks, the client sends the JWT with the request to the backend. The backend then verifies the integrity of the token by checking its signature. If the signature is valid, the backend extracts the user information from the JWT payload and processes the request accordingly, ensuring that the user has the necessary permissions based on their roles and authorization level. Additionally, JWTs often have an expiration time, after which the token becomes invalid, prompting the user to re-authentica...

Book Review - "The Selfish Gene" – A Personal Review and Reflection

Some books explain things. Others reframe how you understand reality. Richard Dawkins’ The Selfish Gene definitely falls into the second category. I went in expecting a book about biology — what I got was a radical shift in how I think about life, evolution, and even human behavior. Right from the opening, Dawkins does something bold: he asks us to stop thinking of evolution as being about individuals or species, and to focus instead on genes. Genes, he argues, are the real players in evolution — long-lasting replicators, using bodies as temporary vehicles to get themselves copied. This shift from the organism to the gene as the central unit of natural selection is what makes the book so groundbreaking. Now, the term “selfish” isn’t meant morally — it’s metaphorical. Genes aren’t conscious or evil. But they “behave,” in an evolutionary sense, as if they’re selfish — doing whatever increases their chances of being passed on. That means creating organisms that are ...
